DC COMMON MODE CHOKE COIL
PLT Series
Compact, lightweight, common mode choke coil for DC power
supplies for common mode noise suppression from several
MHz to several hundred MHz.
FEATURES
I Ideal for suppression of common mode noise in high
frequencies ranging from several MHz to several
hundred MHz.
I PCB mount type makes mounting simple.
I Only negligible influence on 10MHz high frequency signals
(PLT0R53C only).
APPLICATIONS
To meet FCC regulations on digital equipment such as
computers and computer terminal equipment.
To meet VDE regulations on hand-held digital appliances
using AC adapters (suppression of unwanted radiation
from power cords).
Suppression of radiated noise from cable between AC
adapters and sets.
Suppression of radiated noise from DC power supply and
interface cables.
